To au whom, t may concern.-

j Be it known .that JOSEPH Knasenenivs,

deceased, formerly a citizen of the United States, and resident ofCharleroi, in the county of Washington and State of Pennsylvania, did

invent a new and useful Coke-Oven, of which the following is aspecieation.

This invention relates to cokelovens; and its object is to providemeanswhereby the gaseous productsof the coal may be conducted fromralurality ofovens through a common conduit, from which they can be re-Vmoved for heating and other purposes. Y

With the above and other objects i'nview the invention consists ofcertain novel 'features of construction andA combinations of parts,which will be hereinafter more fully described, and pointed out in theclaims.

In the accompanying drawings is shown the preferred form of theinvention.

f In said drawings, Figure l is a view, partly in elevation and partlyin section, of the ovens; and Fig. 2 is a section from front to rearthereof.

Referring to the ligures by characters of reference, 1 is a housin ofvbrickwork, in which are formed a num er of similar par- -allel ovens 2,which extend through the brickwork and are provided With doors 3 at thetwo ends thereof. Inletopenings 4 open into the tops of the ovens andhave closures 5" at ltheir upper ends. A track 6' extends along thebrickwork close to these openings, and cars containing coal for theovens are adapted to be moved therealong into posi'- tion to ldischargethe coal into any one of the openings. Outlet-ports 7 are formed in thewalls of the ovens and communicate with iiues 8, which extend downwardWithin said walls and under the bottoms of the ovens and then open intodischarge-conduits 9, one of these conduits being provided for eachoven. A main or collecting conduit 10 is arranged below and in front ofthe ovens, and the discharge-conduits all open in to it. Each of thedischarge-conduits 9 has a door 11, mounted. in guide and supportingcleats 12, and these doors are adapted to be raised into recesses 13,formed in tlie'top of the conduit l0. A track 14 extends over theconduit 10, and a truck 15 is adapted to travel thereon, said truckcarrying a windlass 16, having a. cable or chain 17 wound thereon andadapted to be placed in engagement with any one of the closures 11. Astack 18 extends from one end of the conduit 10 and is provided with a.suitable dam er 19 for regulating the flow of gases througii the stack.A gas-out let 20 is preferably located below the stack and Within theconduit 10 for conducting the enerated gas to points where it .may beused or various purposes. y

It is thought that the o eration of the ovens will be thoroughlyundbrstood in view of the foregoing description. Coal is discharged intoeach of the ovens 2 and iired in the usual manner,A the damper A9 beinglleft open for a predetermined period, so as to permity the products ofcombustion to pass outward from the ovens through iiues 8 and conduits 9and thence upward to stack 18. Air is of course admitted to the-ovens inany preferred manner. After this combustion has been continued for aproper period the admission of air to the ovens is stop ed and thedamper 19 is closed, whereu on t e coking in the oven's will continue.rlhe gas generated by heating the coal iiows the lues 8 and into thedischargefconduits 9, Whichmay be opened by moving the windlass 16 abovethe closures 1 1 and raising them downward through therewith andthen-locking them in any preferredmanner. The of the ovens will thus bemon outlet 20,' and a considerable saving in the cost of the ovens willthus be made. 4Should it be desired to empty or lill any one 'of theovens, this necessity of closing down the remaining ovens, as itismerely necessary to close the discharge-conduit of the oven to be shutdown. Moreover, the close proximity of the other furnaces will prevent.the oven from cooling to any great extent while the same is beingemptied or filled. Itis of course understood that the walls of the ovenswill retainthe heat to a sufficient degree to fire all subsequentcharges of coal which may be placedv within the ovens after the removalof hot coke therefrom.

The preferred form of the invention has be( a set forth in the foregoingdescription; but th inventor did not limit himself thereto, as he tgasgenerated in all can be done without the was aware that modificationsmay be made therein without departing from the spirit or sacrificing theadvantages thereof, and he therefore reserved the right to make suchchanges as fairly fall Within the scope of the claims.

What is claimed is l. 'l`h e combination with a pluralit)v ol` ovens.each oven havingI :t llue in the bottom thei'eol and independent -lluesin its Walls openingl into the bottom flue; of a collectingconduitdisposed below the ovens, astaek coinmunicating' with said conduit, adisehaigeconduit extending from the bottom llue of each oven and intothe collecting-conduit, a vet-ti 'nity-movable valve for closingcommunication between each dischaige-comluit and the collecting-conduit,a track disposed in front of the ovens and above the collecting-conduit,and n'ieans movable upon the track for actuating the valves.

2. The coml' i1mtion with a plurality o'l' ovens, each oven having allue in the bottom thereof and independent tlues in its wallsl openingrinto the bottom flue; of a collecting-- conduit disposed below theovens, a stack at one end ol' the collooting-conduit, means -lorclosingr communication between the stack and conduit, ar valvedgas-outlet within the collecting-mmdnit, a diseharge-ciinduit extending`from the bottoin tlue ol' each oven to the Colleeting-conduit, aVerticallynu-wable valve for closing,r communication between eachdischarge and thehcollectint' conduits,a track infront of the ovens andabove. the eolleeting-eonduit, and means upon the track for actuatingrany one olA theI valves.

In testimony whereof l have signed my naine to this'specification in thepresence of two witnesses.
